MACHINE FOR PRESSING CIGARS.

Specification of Letters Patent.

Patented Dec. 6, 1921,

Application filed September. 2, 1916. Serial No. 118,293.

(GB-ANTED UNDER THE PROVISIONS THE ACT OF MARCH 3,1921, 41 STAT. I, 1313) To all whom it may concern Be it known that 1, ROBERT -Wonmg'nn, a subject of the German Emperor, residlng at Mannheim, in the Grand Duchy of Baden and German Empire, have invented a new and useful Improved Machine for Pressing Cigars, of which the following is a specification.

My present invention relates to a machine for pressing cigars, which differs essentially and favorably from existing machines used for the purpose by the fact that packets of cigars of different widths and heights,-consisting of cigars of any desired form, can be pressed equally well, and indeed in large or small quantities.

The new device has, further, the advantage that the horizontal press plates necessary for exercising the vertical pressure, are always moved parallel to each other, and indeed also when the press is not uniformly filled. Consequently the jamming which occasionally occurs in existing presses is effectually avoided. This latter object is obtained by the double support of the press plates required for-producing the vertical pressure and of the press tables carrying the press slides and by the adjustability of these parts according to the shape of the cigars to be pressed. In order to be ableto effectually press packets of different breadths and heights and cigars of different forms in the new press, and in order to prevent either a too strong or an insufficient pressure being used, it is absolutely necessary to adjust the horizontal and vertical pressure permissible for the difi'erent forms of cigars before the pressing process commences. For this purpose indicating devices are provided, according to my invention, which enable the horizontal-and vertical pressure to be previously regulated bya foreman and which, during the work, and afterward, show whether the prescribed pressure has been observed. The use of scales in such presses is indeed not new, but heretofore such scales have been used in another connection than in my invention, and the existing devices agree neither in design nor operation with the new arrangement I claim.

On the accompanying drawing representing my invention by way of example,

Figure 1 is a cross section of the machine, Fig. 2, a side elevation of the same, Fig. 3, an elevation, and Fig. 4: a cross section, of the pressure indicator, f

Fig. 5, a side elevation, and Fig. 6. a cross section, of the purchase roll used inthe indicating device, Fig. 7 shows a detail on a larger scale. The cigar press has principal pressing plates 1 which act on pressing bars 2 designed to press against the cigars contained in the press slides.

The principal pressing plates 1 are carried by the spindles 3 having counter screw threads 4 and 5. I 1

On the spindles 3 sit further the pressure rods 8 and 9, which ride on counter screw threads 11 and 12 of said spindles. The tie rods 6, 7 carry the supports 14 and 15 of the tables 13 on which thepress slides are provided, and these supports have slots 14: and 15*. r

The tie rods 6, 7 end in a screw spindle 16 which is connected by a nut with the wheel 31. Said rods 6, 7 have further a slot to allow the spindle 3 to pass through. For the purpose of avoiding superfluous friction the wheel 31 rests in a ball bearing 54, provided in the bearing 55.

The described parts are put into operation by a crank 18, the rotation of which is transferred either to the spindles 3 or to the spur-wheel 31.

For the purpose of driving the spindle 3 there is a miter wheel 20 on the spindle 19 which can be brought into engagement with a miter wheel 21. This wheel 21 sits on a spindle 22, the ends of which carry. miter whee s 23 which engage in the miter wheels 24:.

In order to operate the parts for producing the vertical pressure a spindle 25 is provided, at the lower end of which is provided the miter wheel 26, and at its upper end the bevel wheel 27. The bevel wheel 27 engages in the bevel wheel 28 on the spindle 29, at the opposite end of which sits a bevel wheel 30 which engages in the bevel wheel 31. 32

is a U-shaped crossbar, while 33 and 34: are parts of the frame which end in the feet 35 and 36.

The two devices for obtaining the vertical pressure are connected together by spindles 37 provided with'suitable bevel wheels, and the devices for producing the horizontal pressure by the bevel wheels provided on the spindle 38.

The indicator devices for adjusting the vertical pressure consist of two indicators 39, 40, of which the latter can be adjusted into any desired position by the key 41. The indicator 39 sits on the axis of a roll 42 which is connected with the double roll shown in F ig. 5 by a steel Wire or the like, said wire43 being fastened to the larger part 44 of the roll, while from'the smaller part 45 a wire 46 passes to the movable vertical press bars. Asa consequence every moment of the vertical press bars is transferred to the indicator 3 y a In a quite similar manner the device for measuring the horizontal pressure is ar ranged. In this case the indicator 47 (Fig. 2) is connected with the spindle 3, whose movement is transferred to said indicator. The other indicator 52 is adapted to be.

moved by a key.

The described device isoperated as fol lows: 4

The cigars, in press slides of known con-' moved. These rods have slots 4:8. so that their movement toward each other is not hindered by the tie rods 6, 7.

The press bars 2 for exerting the horizon-1 tal pressure, before beginning the press process, are adjusted according to the packet to be treated, and, by so doing, the bars 48 fastened to the rods 8 and 9 and required to exert the vertical pressure, are automatically adjusted.

As shown inFig. 2, 49 is an end view of a frame, while 49 in Fig. 1 indicates the manner of pressing cigars in layers of twelve or thirteen cigars in a row in the frame 49'. In thedrawing the pressure rods 8, 9 have their widest position.

50 indicates the manner of pressing the cigars in the so called block form, in which each layer only has 10 cigars and the pressing-plates,for the horizontal pressure are correspondingly closer together. The pressing plates or bars 48 for exerting the vertical pressure are shown so near together that their lower members touch each other.

For the purpose of producing the vertical pressure the bevel wheels 51 and 26 are brought into engagement with each other, after the bevel wheels20, 21 have been separated. By turning the crank 18 the tie rods sure.- This is effected by the foreman with a key over the scales. Thereafter the crank 18 is turned until the indicators 39 and 4:7 arrive in the same angular position as the indicators 40 and 52 respectively.

With the object of enabling the operator to ascertain whether the desired pressure has been exceeded the indicators 39 and t'l are provided with tappet-s or stops, so that they force the indicators 40 and 52 out of their position when the pressure is too high. The foreman, who notes the positions given to the indicators 39 and 47', is therefore'able to determine whether his regulations have'been observed. The stops on the indicators 39 and 47 must of course only be on one side, so that when these indicators move back again after exceeding. the maximum pressure the indicators 40 and 52 remain in the highest position to which they have been moved.

The indicators are covered by a'glass plate so that they cannot be tampered with by the workmen.

What I claim and desire to secure by Letters Patent ofthe United States is 1. In a machine for pressing c1gar pack ets of. different sizes, t-he combination with the press table adapted to car the press slides containing the cigars,-o means to support said table on both sides, means to move said supporting means and thus said table vertically, pressing bars against which the packets of clgars are pressed when said press table is vertically moved, and means to adjust the position of said pressing bars accordingto the size ofthepackets ofcigars before exerting the horizontal pressure, sub:; stantially asset forth.

2. In a machine for pressing cigar pack.-

ets of different sizes, the combination with the press table adapted to carry the press slides containing the cigars, of means to support said table vertically, pressing bars against which the packets of cigars are pressed when saidpress table is vertically moved, and horizontally movable pressure rods carrying said pressing bars, substantially as, and for the purpose,'set forth.

3. A machine for pressing cigar packets In testimony whereof I have signed my of different sizes, comprising in combinaname to this specification in the presence of tion, a press table, tie rods adapted to carry two subscribing witnesses. said press table, a screw spindle carrying ROBERT WOERNER.
